Body-wave seismic interferometry on passive seismic data for imaging CO2 reinjection at the Hellisheiði geothermal power plant, Iceland

CO2 and H2S are reinjected at Hellisheiði, Iceland, to reduce the emissions of greenhouse gases. An active-source seismic campaign was done in July, 2021, to image the reinjection reservoir with various seismic methods for consecutive monitoring. At the same time, passive-source seismic data was recorded for imaging.<br/>We process this passive...

Roadmapping the development of a green hydrogen industrial port complex: A case study in an Icelandic setting

The Paris Agreement was created in an effort to enhance the global response to the issue of climate change. To reach this goal, greenhouse gas emissions must be at least 40% below 1990 levels by 2030 and the temperature rise must be kept below 2 degrees Celsius this century. Moreover, the recent fossil fuel price increases, are pressing eye...

Architecture and Feminism?: Housing by Högna Sigurðardóttir and Sigvaldi Thordarson rediscovered through feminist theory

For centuries, women have been underrepresented in society and this has affected the built environment, where prevailing gender ideologies are translated into architecture. In the light of changing social patterns and developments in feminist debate, it’s important to understand and contextualize architecture in relation to gender. This paper...

Impact of the COVID Pandemic on the Icelandic Cruise Ports

Maritime sectors have always been dealing with uncertainties and disruptions. The COVID pandemic confronted the cruise industry with severe and wide-ranging challenges on port infrastructure, operation, and services. Understanding the port performance before, during, and aftermath of the disruption helps stakeholders to increase the preparedness...

North Atlantic Cooling is Slowing Down Mass Loss of Icelandic Glaciers

Icelandic glaciers have been losing mass since the Little Ice Age in the mid-to-late 1800s, with higher mass loss rates in the early 21st century, followed by a slowdown since 2011. As of yet, it remains unclear whether this mass loss slowdown will persist in the future. By reconstructing the contemporary (1958–2019) surface mass balance of...

Earth and Vernacularity: Reviving vernacular architecture in Iceland with rammed earth construction

The growing interest in rammed earth construction globally has yet to reach the Icelandic building industry which lags behind in sustainable construction methods. Despite the rich history of earth construction with local turf, standardized practices and imported materials dominate the building practice today. Earth is a readily available...

Framework for Dealing with Uncertainty in the Port Planning Process

Ports are complex engineering systems that have always been evolving to satisfy the new or changing demands of stakeholders. However, the ever-growing complexity in port sectors in a volatile environment creates a high degree of uncertainty in port planning projects. This study presents a structured framework to deal with uncertainties in the...

Seismological characterization of the Theistareykir geothermal field (Iceland)

In 2017 the National Power Company in Iceland, Landsvirkjun, started the operation of a geother- mal power plant in Theistareykir (Northeastern Iceland). The plant’s operation requires extraction, circulation, and injection of the geothermal fluids to produce energy. These processes depend on the existing fracture network of the reservoir....

A value-based definition of success in adaptive port planning: a case study of the Port of Isafjordur in Iceland

Multiple stakeholders with a wide range of objectives are engaged in a port system. Ports themselves are faced with many uncertainties in this volatile world. To meet stakeholder objectives and deal with uncertainties, adaptive port planning is increasingly being acknowledged. This method offers robust planning, and thereby, a sustainable and...

Stakeholder salience and prioritization for port master planning, a case study of the multi-purpose Port of Isafjordur in Iceland

The dynamic and ever-increasing complex nature of a port system involves a variety of stakeholders with a broad spectrum of involvement and objectives. In the port master planning, to fulfill the objectives of the various stakeholders and manage conflicts and controversies, a stakeholder analysis is carried out. However, effective and timely...

Pathways and watermass transformation of Atlantic Water entering the Nordic Seas through Denmark Strait in two high resolution ocean models

The pathways and watermass transformation of the North Icelandic Irminger Current (NIIC) in the Nordic Seas are investigated by tracing the NIIC watermass in two ocean circulation models: the Modular Ocean Model (MOM) and the Parallel Ocean Program (POP). The two simulations use identical atmospheric forcing and have a horizontal resolution of 0...
